Title: Generating circuit of square wave
Inventor: YAMADA ICHIROU
IPC: H03K3/354
Filed: 1982-04-27
Abstract: PURPOSE:To obtain a square wave signal in a low frequency of about several kHz comparatively stably against temperature fluctuation, by connecting a charge/discharge circuit to a gate of two inverters. CONSTITUTION:A capacitor 5 and a transistor TR4 of constant current operation are combined to form the charge/discharge circuit 6, and an output of the circuit 6 is connected to the gate of the two inverters 9 and 10. The frequency (f) of the square wave is expressed as f=Id/(C.VG9), where Id is the constant current value of the TR4, C is the capacitance of the capacitor 5, and VG9 is the logic level of the inverter 9. For example, Id=10<-9>A, C=10<-12>F and VG9=1V are selected. Those values are possible for realization sufficiently without increase in the occupied area. The (f) in this case is about 1kHz. Since the duty ratio is determined almost with the ratio of VG9 to VG10 (logic level of the inverter 10), the control is done with good accuracy by using the ion implantation technology.

Title: Wafer transporting mechanism
Inventor: WATANABE FUMIO
IPC: B65G47/91
Filed: 1986-03-31
Abstract: PURPOSE:To prevent a slip in position of wafers due to vibration, and storing the horizontal wafers smoothly and reliably in a wafer storing cassette, by inclining the cassette and also inclining a swiveling shaft of a swiveling arm for transporting the wafers. CONSTITUTION:When a piston rod 15 of a cylinder 17 is contracted, a catch plate 12 passes by a position plate 16 without colliding therewith, and is allowed to be lowered to a position 12'. In the pass of the catch plate 12 by the position plate 16, a wafer mounted on the catch plate 12 is transported to the position plate 16, and is slid down into a storing case 13. Thus, the wafer is stored at 1f. As the storing case 13 has an upward inclined opening 13a, there is no possibility that the stored wafer 1f is slipped in position or dropped because of vibration and impact.

IPC: G09G3/36
Filed: 1988-03-25
Abstract: PURPOSE:To improve the display quality of the electro-optic device for which a thin-film transistor array is used by providing an overshoot to the rise of the input waveform to a gate line, thereby steepening the rise and decreasing unequal display. CONSTITUTION:The overshoot 1 is provided in the rise 10 of the input waveform 31 to the gate line of the electro-optic device for which the thin-film transistor (TFT) array is used. An undershoot 2 is provided in the fall 11 of the input waveform 31.

Filed: 1990-03-20
Abstract: PURPOSE:To reduce the fluctuation of resistivity, improve electric characteristics and obtain large margine of a forming process, by using mixed gas of SiH2F2 and NH3 as the forming gas to be introduced into a reaction vessel. CONSTITUTION:Mixed gas of SiH2F2 and NH3 is used as the forming gas to be introduced into a reaction vessel 10 of plasma CVD method, and a silicon nitride (SiN) film is formed on a substrate by using glow discharge decomposition accompanied by chemical reaction.
